6. Embedding GlassFish - Why?
● Why Embedding An Application Server?
● Light packaging for enterprise applications.
● Leverage JEE features in standalone applications.
● Powerful component model through HK2
● HK2 is the foundation for GlassFish v3.
● OSGi compatible modules.
● Dependency Injection.
● Lazy Loading – very fast startup time.
● Very easy to embed.
